Please
check which font is used for → in your Emacs by putting
cursor on that character and type C-u C-x =.  If you do find
that your Emacs is using the Droid Serif font, could you
please send me that font?

The font being used is:

    xft:-unknown-Asana Math-normal-normal-normal-*-14-*-*-*-*-0-iso10646-1 (#x1D5)

The glyph is shown with the correct baseline, but a large descender space (the entire glyph appears to sit above the baseline). Normally, Emacs only makes the line taller when there's a glyph which actually needs the space.
